# System clipboard integration
#
# This file has support for doing system clipboard copy and paste operations
# from the command line in a generic cross-platform fashion.
#
# This is uses essentially the same heuristic as neovim, with the additional
# special support for Cygwin.
# See: https://github.com/neovim/neovim/blob/e682d799fa3cf2e80a02d00c6ea874599d58f0e7/runtime/autoload/provider/clipboard.vim#L55-L121
#
# - pbcopy, pbpaste (macOS)
# - cygwin (Windows running Cygwin)
# - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set)
# - xsel (if $DISPLAY is set)
# - xclip (if $DISPLAY is set)
# - lemonade (for SSH) https://github.com/pocke/lemonade
# - doitclient (for SSH) http://www.chiark.greenend.org.uk/~sgtatham/doit/
# - win32yank (Windows)
# - tmux (if $TMUX is set)
#
# Defines two functions, clipcopy and clippaste, based on the detected platform.
##
#
# clipcopy - Copy data to clipboard
#
# Usage:
#
# <command> | clipcopy - copies stdin to clipboard
#
# clipcopy <file> - copies a file's contents to clipboard
#
##
#
# clippaste - "Paste" data from clipboard to stdout
#
# Usage:
#
# clippaste - writes clipboard's contents to stdout
#
2015-10-04 07:42:24 +00:00
# clippaste | <command> - pastes contents and pipes it to another process
#
# clippaste > <file> - paste contents to a file
#
# Examples:
#
# # Pipe to another process
# clippaste | grep foo
#
# # Paste to a file
# clippaste > file.txt
